Switzerland participates in Task 43 "Vehicle Grid Integration" (VGI) from the IEA Hybrid and Electric Vehicle Technology Collaboration Program (HEVTCP) via Bern University of Applied Sciences (BFH-TI) and Novatlantis GmbH. At the October 2018 meeting in Burgdorf, Switzerland, the IA-HEV Executive Committee approved Task 43 as the follow-on to Task 28 – "Home Grids and V2X Technology". Building on the results of Task 28, this Task aims to explore, identify and give answers to the gaps preventing the electric vehicles to be fully integrated in the electrical grid. In addition, it is also intended to improve the joint work between the electric sector and the mobility sector, which is a key point for the real energy transition. Activity mainly consists of expert workshops for researchers, industry and policy makers to work together in order to tackle the various technical, regulatory and social challenges of VGI. Ms. Cristina Corchero from the Catalonia Institute for Energy Research (IREC) is the Operating Agent of Task 43. The kick-off meeting took place in May 2019 in Lyon, France. Followed by an international workshop on regulatory challenges for VGI, held on November 2019 in Brussels, Belgium. Participants countries are: Spain, Great Britain, Switzerland, Korea, Ireland, France, Belgium, Italy, Canada, Denmark, Netherlands, Germany. This report provides an overview of the work carried out through Task 43.
